Soil bacterial community responses to warming and grazing in a Tibetan alpine meadow
Warming and grazing significantly affect the structure and function of an alpine meadow ecosystem. Yet, the responses of soil microbes to these disturbances are not well understood. Controlled asymmetrical warming (+1.2/1.7 degrees C during daytime/nighttime) with grazing experiments were conducted...
